Answer:

16.5

Step-by-step explanation:

A is the correct answer

Step-by-step explanation:

If you plug y=x+10 in for the Y variable you just have to solve by multiplying.

1.) It should look like this:

2x + 3(x +10) = 40

2.) You will distribute the three which will make the equation look like this:

2x + 3x + 30 = 40

3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.

but 16.5 is the answer

Step-by-step explanation:

The correct answer is option c. 16.8%, which means that I can have an expected return of 16.8%.Let us go through the solution to know how option c. is the correct one.

The expected return of the portfolio can be calculated by weighing the expected returns of each investment based on their respective percentages in the portfolio.

In this case, with 40 percent invested in an investment with an expected return of 12 percent and 60 percent invested in an investment with an expected return of 20 percent, we can calculate the expected return of the portfolio as follows:

Expected Return of Portfolio = (Weight of Investment 1 * Expected Return of Investment 1) + (Weight of Investment 2 * Expected Return of Investment 2)

= (0.40 * 0.12) + (0.60 * 0.20)

= 0.048 + 0.120

= 0.168

Therefore, the expected return of the portfolio is 16.8%. Hence, the correct answer is option c. 16.8%.

Answer:

cos(x) = ???

so the maximum cosine can be is 1 and that happens when x = 0

I'm pretty sure that's what you meant...

The value of x where the cosine function attains a maximum value is 0.

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

Cosine function.

The value of cos 90° is 0.

The value of cos 0° is 1.

The value of cos 30° is √3/2.

The value of cos 60° is 1/2.

We see that the cosine function has the maximum value at zero degrees.

Thus,

Cos x has the maximum value at x = 0.

the beta of the portfolio is 0.8.

The capital asset pricing model (CAPM) formula is used to determine the beta of a portfolio.

CAPM formula: E(rP) = rf + β[E(rM) - rf]

Given:
E(rP) = 13%
rf = 5%
E(rM) = 15%

Substituting the values into the CAPM formula:
13% = 5% + β[15% - 5%]

Simplifying:
8% = 10β

β = 0.8

Therefore, the beta of the portfolio is 0.8.

The beta of a portfolio with E(rP) = 13%, if rf = 5% and E(rM) = 15%, is 0.8.

To find the beta (β) of a portfolio, we can use the Capital Asset Pricing Model (CAPM) formula:

E(rP) = rf + β * [E(rM) - rf]

Where E(rP) is the expected return of the portfolio, rf is the risk-free rate, and E(rM) is the expected return of the market.


Given E(rP) = 13%, rf = 5%, and E(rM) = 15%, we can plug these values into the CAPM formula and solve for β:

13% = 5% + β * (15% - 5%)

Step 1: Subtract the risk-free rate from both sides:

8% = β * 10%

Step 2: Divide both sides by 10% to isolate β:

β = 8% / 10% = 0.8


The beta of the portfolio is 0.8 (rounded to 2 decimal places).

Answer:

length of BC = 5 1/4 feet

Step-by-step explanation:

Area of a triangle = 1/2×base×height

Area = 4 3/8 square feet

Base = AC= 1 2/3 feet

Height = BC = ?

Area of a triangle = 1/2×base×height

4 3/8 = 1/2 × 1 2/3 × height

35/8 = 1/2 × 5/3 × height

35/8 = 5/6 × height

Height = 35/8 ÷ 5/6

= 35/8 × 6/5

= (35 × 6) / (8 × 5)

= 210 / 40

= 5 1/4 feet

Height = BC = 5 1/4 feet

length of BC = 5 1/4 feet

Using a trigonometric ratio we can find the value of x is approx 4.76

What is trigonometric function?

Mathematical trigonometric functions connect the angle of a right-angled triangle to the ratios of its two side lengths. In all areas of study that involve geometry, such as geodesy, solid mechanics, celestial mechanics, and many others, they are widely used. Fourier analysis is commonly used to study periodic events since it is one of the most fundamental periodic functions.

An essential trigonometric function that can be used to calculate the value of "x" is the tangent function.

Given :

The right-angle triangle ABC.

AB = x

BC = 4

∠A=40°

We know,

tanθ= P/B

Where the perpendicular is P and  the base is B of the given triangle.

So, tan40°= 4/x

X=4/tan40°

X≅4.76

Hence the value of x is 4.76.

\(\huge\boxed{Diameter=11cm}\)

Step-by-step explanation:

Important information:

Circumference of a circle= \(\pi*diameter\)

Method:

To work out the diameter, we would need to divide the circumference of 34.54 by pi, which in this case is 3.14, this gives us 11cm. This is because we are simply rearanging the formula of the circumference of a circle to make the diameter the subject.

Step By Step:

1) Rearange the formula to make the diameter the subject.

\(diameter=\frac{circumference}{\pi}\)

2) Divide 34.54 by 3.14(\(\pi\)).

\(34.54/3.14=11cm\)

There is a a circle whose circumference is 34.54 cm. Find the diameter of the circle. Remember use 3.14 for π.

- To know the diameter divide 34.54 cm by pi (π) to get the answer.

\( \large \tt d = \frac{34.54}{\pi} \\ \large \tt d = 11cm\)

Therefore, the diameter of the circle is 11cm

3(w-2)+4u , 2(2u-3)+3w , or something else.

The quadratic equation whose roots are x = - 1 / 3 and x = 4 is equal to 3 · x² - 11 · x - 4.

Algebraically speaking, we can form an quadratic equation from the knowledge of two distinct roots and the use of the following expression:

y = (x - r₁) · (x - r₂)

If we know that r₁ = - 1 / 3 and r₂ = 4, then the quadratic equation is:

y = (x + 1 / 3) · (x - 4)

y = x² - (11 / 3) · x - 4 / 3

If we multiply each side by 3, then we find the following expression:

3 · y = 3 · x² - 11 · x - 4

The probability that each category is kept together is 0.000079.

To calculate the probability of each category being kept together, we need to calculate the total number of ways the books can be arranged on the shelf, as well as the number of ways that the books in each category can be arranged together.

First, let's calculate the total number of ways the books can be arranged on the shelf:

Total number of ways to arrange the books = 9! = 362,880

Now, let's calculate the number of ways that the math books can be arranged together:

Number of ways to arrange the 4 math books = 4! = 24

Similarly, the number of ways to arrange the history books together and the science books together are:

Number of ways to arrange the 2 history books = 2! = 2

Number of ways to arrange the 3 science books = 3! = 6

Since there are three categories of books that need to be kept together, we need to multiply these probabilities together to get the total probability:

Total probability = (number of ways to arrange math books) x (number of ways to arrange history books) x (number of ways to arrange science books) / (total number of ways to arrange books)

Total probability = (24 x 2 x 6) / 362,880

Total probability = 0.00007916
